ATTRA - National Sustainable Agriculture Information Service is created and managed by the National Center for Appropriate Technology (NCAT) and is funded under a grant from the United States Department of Agriculture's Rural Business-Cooperative Service. It provides information and other technical assistance to farmers, ranchers, Extension agents, educators, and others involved in sustainable agriculture in the United States.



ATTRA services are available to farmers, ranchers, market gardeners, Extension agents, researchers, educators, farm organizations, and others involved in commercial agriculture, especially those who are economically disadvantaged or belong to traditionally underserved communities. Anyone may read or download publications from our Web site, but we do not have the staff resources to respond to queries to our office from hobbyists and students.
